Vague, indistinct (4)
I believe the answer is:
hazy
I believe this is a double definition.
'vague' is the first definition.
(I've seen this before)
'indistinct' is the second definition.
(similar in meaning)
(Other definitions for hazy that I've seen before include "Vague, ill-defined" , "Unclear" , "Nebulous" , "Blurred" , "Obscured" .)
